Battery Connection
The Home Standby Generator is supplied with a 12Volt
DC,AGM type, 33 Amp-Hour, valve regulated battery. It is a
sealed, lead-acid rechargeable battery. It is installed in the
unit and the battery cables are connected at the factory.The
unit’s 15 Amp fuse, which isolates the battery and prevents
the unit from starting, has been removed for shipping.The
battery will lose some charge charge prior to installation of
the generator. If battery voltage is below 12Volts, charge the
battery.
IMPORTANT: If battery voltage is below 5 Volts, it may
not take a charge and you will need a new battery.
Charging the Battery
If it is necessary to charge the battery, proceed as follows:
1. Set the generator's “AUTO/OFF/MANUAL” switch to
OFF.
2. Remove the 15 Amp fuse from the control panel.
3. Disconnect the negative battery cable to the negative
battery terminal (indicated by NEGATIVE, NEG, or (-).
4. Charge battery with battery charger at 2 Amps until
battery holds 12 Volts.
NOTE:With the battery installed and utility power
available to the Automatic Transfer Switch, the battery
receives a trickle charge whenever the engine is not
running.This process may take up to 72 hours to fully
charge a battery from 5 Volts.The trickle charge cannot be
used to recharge a battery that is completely discharged.
5. Connect the negative battery cable to the negative
battery terminal (indicated by NEGATIVE, NEG, or (-).
6. Ensure hardware on both positive and negative battery
terminals is secure.
7. Reinstall the 15 Amp fuse in the control panel.
8. Set the generator's “AUTO/OFF/MANUAL” switch to
AUTO.

Storage batteries give off explosive hydrogen gas
during recharging.
Slightest spark will ignite hydrogen and cause
explosion.
Battery electrolyte fluid contains acid and is
extremely caustic.
Contact with battery contents will cause severe
chemical burns.
A battery presents a risk of electrical shock and
high short circuit current.
